Is it possible to make a parameterized scripted pipeline in Jenkins by listing the parameters in actual script, not in job config

Question

In a declarative pipeline, I can specify the parameter that the pipeline expects right in the pipeline script like so:

pipeline {
   parameters([
    string(name

You can use Jenkins job DSL plugin for generating jobs, pipelines, multi-branch pipelines... The DSL allows the definition of a job, and then offers a useful set of functions to configure common Jenkins items. A configure is available to give direct access to the config.xml before generating the job. With parameters block you can then easily define any type of parameters with their default values and description. Note that this plugin is also compatible with git and other version control systems.

jobDsl scriptText: ''' job('example') {
    parameters {
        stringParam('Parameter Name', 'Default Value' , 'Parameter Description')
    }
    scm {
        perforceP4('p4_credentials') {
            workspace {
                manual('ws_name', '//depot/Tools/build/... //ws_name/build/...')
            }
        configure { node ->
                    node / workspace / spec / clobber('true')
            }
        }
    }
}'''

I found a solution by experimentation so want to share it:

node {
  properties(
    [
        parameters(
            [string(defaultValue: '/data', name: 'Directory'),
             string(defaultValue: 'Dev', name: 'DEPLOY_ENV')]
            )

    ]
    )    

  ....
}

Answer 3

I did create it outside and it worked! Also, I'm using the boolean value and it's working like a charm on a scripted version

// Parameters for the build
properties([
  parameters([
     booleanParam(name: 'DEPLOY_SHA', defaultValue: false),
  ])
])

podTemplate(name: ptNameVersion, label: ptNameVersion, containers: [
...
...
] 

It shows the parameter

I highly recommend using the "Snippet Generator" for first time use of figuring this out. It will allow you to use a GUI that looks maybe exactly like the snapshot you shared above, to fill out the settings you want, and generate the appropriate syntax. For this question in-particular, select the sample step "properties: Set job properties" from the Snippet Generator

You can access the "Snippet Generator" from any Jenkins server by going to the /pipeline-syntax endpoint.

For more info on the snippet generator see: https://jenkins.io/doc/book/pipeline/getting-started/#snippet-generator
